Best ResponseYou've already chosen the best response.0First, we need to solve the first equation for x. We get\[x = (20/7)y + 2\] Then we substitute this expression into the second equation. This yields \[10y  2((20/7)y + 2) = 4\]Solve this for y and plug the value of y back into our expression for x. Let me know what you get.
